Stopping the Radar When you enter standby mode, the antenna will stop spinning, but the magnetron will remain charged. This means that the Radar can be quickly turned on again without having to warm up. To place the GMR 404/406 in Standby mode: 1. From any page, press and hold the FCTN key. 2. Using the ROCKER, highlight Yes and press ENTER. Note: When the radar is placed into standby mode, the GMR 404/406 antenna will reduce its spinning speed for approximately 15 seconds, then stop perpendicular to the length of the boat, or as defined by the Front of Boat Offset.
